To all whom it may concern:

Be it known that I, ALBERT H. MORTON, a citizen of the United States, residing at Lowell, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements in RovingeGreels for Spinning-Frames and the like; and I do hereby declare thefollowing. to be a full,

clear, and exactdescription" of the -invention, such as-Will enableothers skilled. in the art :to which it appertains t0 makeand use the same. 1

The present invention relates to-an im provementin roving creels for spinning. frames and the like.

Roving. bobbins/supplying roving to spinning framesaresupported in-a creel mounted on the frame. In cases Where double roving is used, a so-called two-story creel is used-wherein the bobbins are mounted on skewers supported in vertical position revolving in porcelain steps so that practically theonly resistance offered totherotation of the bobbin is that between the footof the' skewer and the porcelain-step. Thelimited space" inwhich the bobbins are supported requires the use of two bobbins,- onebehind i the other, on each side of the frame, and-inasmuch as the usual size of a-bobbinfor a fr'amein Whichi'thespindles arespaced 2% inches apart-is 3!; 013 4: inches in diameter, it

is apparentthat thefull bobbins-have only 1- .inch clearance.- In replenishing the roving supply the skewers have to be'removed from their bearings to remove an empty bobbin I and to replace-it With a full one, and upon the exhaustioni of' one of the rear bobbins, the operative is required to take out the front bobbin as well as the empty bobbin, and then, after-putting the former frontbobbin in the place of the empty bobbinyto put another full bobbin in the front position and piecethe roving. The inaccessibility of the rear bobbin Without first removing the front bobbin-1s one of the thingswhich renders tending this form of creel laborious forth'e operative. Besides, it is apparent that where the bobbins are placed so close-together asis. required in this creel, the rear bobbins are not easily observable, particularly-as it is the usual practice to put the full bobbin in the front position. Furthermore, in 'cleaning the top of the frame betweenthe roller" beams, considerable care is required to be-exercised, as but a sllght contact Withtherov- :mg or a bobbin is suliicient to break theroving. a

The object of the present invention is to reorganize and improve the construction of the rovmgcreels for spinning frames in or= der to secure accessibility of the bobbin for S0, in the creel forming the subject'of thisinvention, the bobbin is so mounted as tobe' capable of turning by the exertion of a strain thereon within the tensile strength of roving .and Without stretching or breaking it, and

the creel pins for supporting the-bobbinsare varranged in such'a-Way as to conduce totheir easy removal and replacementfor the purpose. of replenishing the roving supply; so that they are conveniently observableby' the operative, and so that they shall be capable of being rotated by strains exerted there on Within the extremely slight strengthof the roving. To these ends the rotarycreel pins for carrying the bobbins are mounted upon bearings of sufficiently low friction to permit the rotation of the bobbin Without the exertion on the roving of a stretching or breaking strain. Furthermore,- the creel pins are'so'located that all of the bobbins are accessible for the removal of empties and theputting on of full'bobbins Without requiring the'disturbance of more than the-particular bobbin necessary to be replaced. This-isac-fl complished in the illustrated embodiment by arranging them in inclined position one The creel posts carry a series of rail bracketsabove the other on a creel frame, so that all position before the parts are forced to- 65 of the creel pins are freely accessible. This arrangement con'duces not only to reducing the labor of the operative, but to facility of cleaning the frame, as the top of the frame is freely accessible without interference-with or liability of striking the bobbins.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 is a transverse sectional elevation of the creel, and Fig. 2 is an enlarged longi- 1 tudinal sectional elevation of one of theretary creel pin's.

The supports 1 of the frame of the machine carry the roller beams 2 upon which the roll stands 3' are mounted, supporting upon the upper surfaces of the supports.

The creel posts 6 are supported in the supports 1, being secured therein by set screws 7, and passing through holes in the cover 5.

8 secured totheposts by set screws 9. To the upper ends of the creel posts are secured the pan brackets 10 by means of set screws 11. On the pan brackets is secured the pan 12 for holding a supply of roving and receiving empty bobbins. The rail brackets have inclined surfaces adapted to receive the rails 13, the brackets being provided with lips to engage the edges of the rails so as to aflord adequate support therefor. The rails 13 consist of bars of iron secured to the rail brackets and extending longitudinally of the machine, inclined as shown, to hold the ,creel pins projecting outwardly in opposite directions at right angles to the rails. The

creel pins 14 forthe bobbins are revolubly mounted onthe rails 13. mounted on a stud 15- having a reduced threaded end which is received in a hole inthe creel rail and secured by. means of a nut. The creel pin consists of a bottom sleeve 16,

a tube 17 and acap 18, and is supported on two ball bearings 19 and 20. The bottom sleeve 16 is provided with an outwardly projecting shoulder forming a bobbin rest, and with a ball race for the lower ball bearing .19. The other member of the bearing 19 is formed by cutting a groove in the stud 15.

The cap 18 is provided with a ball race for the-upper bearing 20, the other member of which is formed upon the end of the stud 15.

The creel pin is assembled on the stud 15 by pressing the tube 1'1 upon the bottom sleeve 16, inserting the balls of the bearing 19and supporting the parts in proper posi- .tion with relation t6 each other, and then forcing the cap 18 into the end of the tube 17, the baHs'of the bearing 20 being placed Each pin is' gether. The cap 18 is provided with a shoulder which engages'the end of the tube 17 the portion above the tube being of the same size as the outside of the tube. Beyond this, the end of the cap is made frusto-conical to facilitate placing the bobbins on the creel pin. The creel pin,. as seen in F ig. 1, is made sufliciently long to extend into the bobbin beyond its center of gravity. T-wo rovings (from two bobbins) are, as illustrated, led to each roving trumpet or guide 21 which directs the rovings to the drawing rolls.

The lowermost bobbin is locatedga little distance above the top of the frame so as to afford room for swinging up the cap bar containing the top rolls, and therefore the top of the frame .is easily accessible for cleaning. Each of the bobbins of this creel is directly accessible to the operative without interference with any other bobbin, so

when a bobbin is exhausted the operative replace it with a full bobbin with the other hand, and immediately piece the roving. This reduces the amount of labor imposed upon the operative in replenishing the rov- .ing,-not only by reason of the elimination of the removal of the front bobbins to get at the rear ones, but by reason of the fact that there is no skewer to be removed with and replaced with the bobbin. Again, every can remove the empty bobbin with one hand,

bobbin is .in plain, full sight of the operative, andmay be continuously and easily observed. 1

The construction is simple and therefore chgiip. It is also strong, and therefore dura e. V

It is essential, it will be observed, that the bobbins be capable of being rotated by the exertion thereonfof a very slight strain within the stretching and breaking strength of the roving to which such strain is transmitted, soit is necessary that the creel pins have low-friction bearings, and while ball bearings are preferred because of the small amount of friction which they develop, other forms of low-friction bearings may be used, and are within the purview of the invention.

The invention, viewed in its broaderaspects, contemplates any form of roving creel for spinningfralnes and the like wherein the creel pins are accessible, visible, and

mounted in inclined position upon low-friction bearings.

Having thus the invention, what of the roving runs from the bobbins to the roving guides for the rolls, supported upon 1,144,?20 low-frictibn bearings s0 that the resistance bins and the putting on of full bobbins with-- to rotation of the bbbbins'is so small as to out interference with other bobbins, substanbe Within the strength of the roving to overtialiy as descrlbed.
